ToUSB-A
The answer
Short answer No. Do not connect two computers with a plain USB-A to USB-A cable; that needs a purpose-built transfer bridge.
Watch out
Direction and exact products matter
Connectors that fit do not prove a connection works. Check that the exact cable or adapter is documented for USB-A → USB-A, and that both devices support what you need.
